However, during a monologue, the ex-One Direction band member made a subtle dig at his former friend Zayn Malik.
"I'm not in a boy band anymore. I'm in a man band now. I was in a band called One Direction," Harry began.
"I love those guys. Niall, Liam, Louis..." the "Watermelon Sugar" singer then pointedly struggled to try to remember the fourth band member's name (Zayn), before concluding "and, uh, Ringo! Yeah, that's it."
A lot of Zayn Malik fans had a huge issue with Harry's jab, calling it insensitive or immature.
"Joke or not, imagine the twitter outrage if Zayn went on international TV and threw shade at Harry!" exclaimed another fan. "Zayn hasn't said a word about them yet with the exception of Niall they all can't seem to stop with the pettyness!" they continued.
However, as beloved as Harry is by his fans, they were right there by his side defending him.
One fan wrote: "The joke was that Ringo was the first to pursue a solo career in The Beatles just like Zayn was the first in One Direction, like I don't know why everyone thinks it's so deep."
Another said: "We all know Harry didn't have ill intention, we all know SNL wrote the joke, we all know Harry loves Zayn. We all know it's gonna blow over in 2 days. It's getting really sad".
Neither Zayn or Harry have addressed the 'drama', and we don't think they will. Right now, Harry is gearing up to release his second solo studio album on December 13. The star has already released two singles, "Lights Up" and "Watermelon Sugar," which he performed on SNL.
As for Zayn, rumour has it that he's busy getting back with ex-girlfriend Gigi Hadid!
